i have a lenovo s430, since kernel 3.14, my mouse stop to work after a few second, minute. If I stop using the mouse for a few seconds, the mouse stops working. When I turn it off, the bluetooth applet on my desktop shows it as connected indefinitely. I can fix this situation if i do a suspsend to ram. my card Dual Band Wireless-AC 7260 Bus 001 Device 003: ID 8087:07dc Intel Corp.
Does disabling USB auto-suspend for the device help? You can do that e.g. with the powertop tool or by doing: echo 'on' > '/sys/bus/usb/devices/1-3/power/control'
it seem to fix the problem, after 2 hours, that work without problem
if i do a supsend to ram, i seem i need to rerun this command
Do we need to get a USB quirk in for this one to stop it autosuspending.
I believe the plan is to revert the patch that enabled auto-suspend for this hardware to begin with. This revert should be going to the stable tree as well as the 3.15-rc series.
For the record, the revert has already made it to Linus's tree and is part of 3.15-rc5.
